What do you think we should replace it with? Some years back, when my country replaced a corrupt, entrenched coalition govt of 60+ years, the winning party sort of looked around and said: ‘uh… huh, OK, we won. We werent expecting to win. Now what? We have no plan. Lolz?’
In that light, what do you think should replace the big C, and how do we ensure human nature doesnt juat exploit it for a few individuals benefit?
problem is OP you don’t just bring down/destroy/disappear capitalism
capitalism is an umbrella term for the economic system that emerged from the most basic early trade/money systems/financialisation
so in reality you start with capitalism and change it to enable things you like
anyone that doesn’t start answering your question with capitalism is a bullshit fantasist
judging by the other replies you’ve had that’s what you got. that’s why these transition plans to communism are so threadbare and disfunctional. they are just hand-wavey dreams
Even with socialism the use of currency is a useful tool for allowing people to acquire what they need then what they want. Capitalism as we know it now and how it has been needs to fall but that doesn’t mean there isn’t some usefulness to be gained from it. And there will be a huge transition period as well that will likely take a couple generations to then start rotating away from capital being desirable.
